Olivier Sterck is Associate Professor at the University of Oxford and lead economist of the Refugee Economies Programme (REP). His research is multidisciplinary in scope, building bridges between development economics, health sciences, and refugee studies. With colleagues from the REP, he has been collecting and analysing data on more than 15,000 refugees and members of host populations in Kenya, Uganda, and Ethiopia. In partnership with the World Food Programme, Olivier has been analysing the impact of various cash transfer models on the socio-economic outcomes of refugee households and refugee businesses in the Kakuma refugee camp and the Kalobeyei settlement. With the World Bank, Olivier has been evaluating the impact of a cash-for-work programme in Comoros and a cash grant and training programme in Tunisia.
